WELL-CAP.

SPECIFICATION forming part of Letters Patent No. 738,126, datedSeptember 1, 1903.

Application filed June 24,1903.

To all whom, iv 17mg; cancer-7" Be it known that LWILLIAM F. SHUTT, acitizen of the United States, residing at Onward, in the county of Cassand State of Indiana, have invented new and useful Improvements inWell-Caps, of which the following is a specification.

This invention relates to well-caps.

The objects of the invention are in a ready, simple, andthoroughly-feasible manner to dispense with threaded unions inassembling the casing-pipe and pump-pipe of a well, to preclude entranceof surface-water to the well, as also animalssuch as frogs, toads, andthe like-thus to keep a well in thoroughly clean and sanitary condition,and,finally,generally to improve and simplify the construction ofdevices of this character.

With these and other objects in View, as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts ofa well-cap, as will behereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts,there is illustrated one form of the embodiment of the invention capableof carrying the same into practical operation, it being understood thatthe elements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing from thespirit thereof. In the drawings, Figure 1 is a view in side elevation,exhibiting the attachment in position. Fig. 2 is a vertical longitudinalsection through the assembled device. Fig. 3 is a View in top plan. Fig.4 is a sectional view of a slightly-modified form of bonnet.

The well-cap of this invention embodies three elementsa base-ring 1, agland 2, and abonnet 3. The base-ring and the gland are each providedwith perforated ears at, in this instance two in number, through whichpass the assembling-bolts 5, nuts 6, carried by the bolts, serving toclamp the parts of the cap together, and thus present at once a rigidand a water-tight union and one that will successfully withstand thejars and vibrations imparted to it incident to the operation of theSerial No.162,938. (N0 model.)

pump. It may be remarked at this point that the well-cap of thisinvention is adaptable for use in connection with any closed or drilledwell havingan'independentpump-pipe. The inner wall of the pipe-openingof the basering is provided with a beveled seat 7, between which and thelower oppositely-beveled end 8 of the bonnet is disposed a packing 9, ofany suitable material, said packing operating in a well-known manner topreclude the entrance of foreign matter to the interior of thecasing-pipe 10. This pipe is held within the bonnet by a jam-bolt 11,which is threaded into a boss 12 on one side of the bonnet and, as shownin Fig. 2, impinging the casingpipe in such manner as to hold it in itsad justed position. While but one jam-bolt is herein shown, it will beobvious that two or more may be employed without changing the spirit ofthe invention, and, as this will be readily understood, detaileddescription thereof is deemed unnecessary. The top of the bonnet isprovided with a depending tn bular teat 13, constituting a bushing orpacking-holder, the lower end of which is provided with adownwardly-beveled flange let, constituting a seat, and between thisflange and the oppositely-beveled lower end 15 of the gland is arrangeda packing 16, which when the parts of the device are properly assembledwill positively preclude entrance of any foreign matter to the well orcasingpipe. The gland is provided at right angles to the ears 4 with ajam-bolt 17, which is adapted to be turned into engagement with thepump-pipe 18, thus to hold it rigidly clamped in position. To strengthenthe gland, the same is provided on its upper face with reinforcing-ribs19, cast integral with the structure, in the usual or any preferredmanner.

In connecting the pump-pipe and casingpipe with this device thebase-ring and bennet are first positioned upon the casing-pipe, and thejam-bolt 11 is tightened to clamp the bonnet to the casing-pipe. Thepump-pipe being properly positioned and having the gland 2 thereon, thelatter is forced down into the teatof the bonnet, and the jam-bolt 17 isthen tightened, thus to clamp the gland to the pump-pipe. The bolts 5are then passed through the cars of the base-ring, and the gland and thenuts 6 thereon are seated, thereby forcing the bonnet and the glandagainst the packings 9 and 16, respectively, which have previously beenplaced in proper position. WVhe'n the parts are thus assembled, an airand water tight joint will be effected between the pump-pipe and thecasing-pipe, which will operate positively to preclude the entrance offoreign substances to the well.

By the provision of the smooth interiorlybored bonnet and smoothinteriorly-bored gland, in conjunction with the jam-bolts 11 and 17 andbolts and nuts and 6, respectively, the necessity for employing threadedconnections is entirely obviated, and a union between the parts of thedevice and the different pipes will be as rigid and lasting in characteras will be secured by the employment of threadedunions. Moreover, by theelimination-of threads separation of the parts may be readily effected,as there will be no rust-bound joints to be forced apart with attendantdanger of breakage.

It will be obvious that in carrying the invention into practicaloperation various changes in the proportion and construction of theparts may be resorted to and still be within the scope of the invention;For instance, as shown in Fig. 4, the bonnet may be constructed withoutthe tubular teat 13, thus to adapt it for use in connection withdifierent-sized pipes. Where this form of bonnet is used, the pipe willrest against the under side of the bonnet and will be held in positionby a jam-bolt in the same manner as that shown in Fig. 2.

Having thus described the invention, what is claimed is- 1. A device ofthe class described embodyingabonnet-carrying clamping 1neans,abasering,agland embodying clamping means, and means for adjustably connecting thebasering and the gland.

2. A device of the class described, embodying a bonnet having its upperportion provided with a bushing-holder, and with clamping means, abase-ring, a gland adapted to engage the bushing-holder and providedwith clamping means, and means for adjustably connecting the base-ringand the gland.

3. A device of the class described, embodying a bonnet having its upperportion provided with a hollow depending teat provided with an inclinedflange, a base-ring engaging the lower portion of the bonnet, a glandengaging the teat, and clamping means carried by the gland and by thebonnet.

4. A device of the class described, embodying a base-ring provided withperforated ears and having an internal beveled flange, a bonnot adaptedto fit within the ring and having its lower end oppositely beveled tothat of the base-ring and its upper portion provided with a hollowdepending teat provided with a beveled flange, clamping means carried bythe bonnet, a gland adapted to [it within the teat and having its lowerend oppositely beveled to that of the teat-flange, and its upper portionprovided with perforated ears, clamping means carried by the gland, andadj usting-bolts engaging the ears of the basering and of the gland.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
